Portanto, o gatilho 112 não é mais impedido de rodar e desengata-se do acoplamento de acio 5 namento 121, desse modo estendendo a seringa 122.126 within housing 112, cutout 152 is positioned above the end of protrusion 154 allowing it to pass over protrusion 154 when a downward force is applied to trigger 112. Therefore, trigger 112 is no longer prevented from rotating and disengaging from actuation coupling 5 to 121, thereby extending syringe 122.

A protuberância 154 compreende uma gatilho 114 inclui uma segunda parte 162 que se estende dentro do recorte 152 a partir da primeira parte 150 do gatilho 114 e q je está disposta para se comunicar com a segunda parte 162 seguindo a rotação do gatilho 115 de 10 modo que a primeira estria 160 é travada sobre a segunda parte 162, desse modo impedindo o movimento do gatilho 114 de su para sua posição de repouso.The protrusion 154 comprises a trigger 114 includes a second part 162 which extends within the cutout 152 from the first part 150 of the trigger 114 and which is arranged to communicate with the second part 162 following the rotation of the trigger 115 so that the first groove 160 is locked on the second part 162, thereby preventing the movement of the trigger 114 of its to its resting position.

O mecanismo de travamento 116 inclui forma de braços resilientes 171, que âtuam contrai a superfície interna do 15 alojamento 112 para orientar o mecanismo de travamento 116 e a luva deslizante 126 em uma direção fora da abertura 118. Esta maneira, seguindo a ativação do gatilho 112, a primeira estria 160 é travada sobre a segunda parte 162 do gatilho 112, desse modo mantendo o gatilho 112 em sua posição ativa.The locking mechanism 116 includes the form of resilient arms 171, which contract the inner surface of the housing 112 to orient the locking mechanism 116 and the sliding sleeve 126 in a direction outside the opening 118. This way, following the activation of the trigger 112, the first groove 160 is locked on the second part 162 of the trigger 112, thereby maintaining the trigger 112 in its active position.
